In terms of the energy density, hydrogen storage has the highest volumetric energy density of 500–3000 W h/L depending on the storage methods (e.g., compressed gas, liquid, physical/chemical adsorption, etc.). As an extremely flammable gas, however, the technical requirements for hydrogen storage are high. The energy storage density of the LAES is an

Technical merits make redox flow batteries well-suited for large-scale energy storage. Flow batteries are normally considered for relatively large (1 kWh – 10 MWh) stationary applications with multi-hour charge-discharge cycles. Flow batteries are not cost-efficient for shorter charge/discharge times.
